Baldur's Gate: Enhanced Edition

So, I lost the "Sea Charts' that the dude needs for the islan d quest, the ones you get from baldur's gate. I don't know if I sold them, dropped them, or if a glitch stole them away. They were just gone when I went to turn in the quest.

I have been searching every shop I can find in the game to see if I sold them and so far I can't find a thing.

Is there any other way to aquire the charts or am I just boned? I will gladly use a cheat if I have to.

you probly will have to use a cheat to get it back. first off you generaly cant sell quest items unless their something you can use yourself (I.E. armor or swords) if you dropped it, its GONE. Finaly same thing goes for it a glitch wisped it away but its not all that important unless its a game ender right? i've play BG:TOTSC for years but i barly remember that quest... so i dont know if thats a game ender of not.
